Three day labour here and dp really bloody needed the flapjacks I shoved in my hospital bag as an afterthought. He didn't leave my side the entire 40 hours we were at the hospital, because I was having a hell of a time.
He gave my bag of toffees away to the midwife though and i was gutted.
The birth was so long and exhausting and with complications (theatre, spinal block, pph) that when I was in post natal I hadn't even the energy to get toast. I really bloody needed those toffees (three years on and I'm still not over it).
The hospital is located quite far out of town so no takeaways or mcd's nearby, even. And no vending machine except 7 floors away in a and e
I think packing food for your birth partner is essential, as you really don't know how long that labour will go on for (mine was 70 hours, 40 of those in the hospital. I had one muller light yoghurt in that time. Dp only the snacks I packed).
If your labour is quick and hassle free, great. You can snack on them while breastfeeding.
Flapjacks, cereal bars, nuts and dried fruit, drinks in a sports bottle (I had powerade which I don't normally drink. Omg bloody fantastic pick me up, restorative in post natal after that long labour).
